TROLLElY-GUARD.

SPECIFICATION forming part of Letters Patent No. 777,052, dated December 6, 1904.

Application filed February 26, 1904. SerialNo. 195,416. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE W. VVA'rsoN, a citizen of the United States, residing at Kearney, in the county of Hudson and State of New Jersey, have invented certain new and useful improvements in Trolley-Guards; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

The objects of this invention are to secure greater simplicity of construction, to reduce the cost of manufacture and yetprovide a guard for trolleys of great efliciency, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved trolleysguard and in the arrangements and com binations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a side elevation of the improved guard, and Fig. 2 is a perspective view of one of the guarding-plates thereof. Fig. 3 is a front elevation of my improved device.

In said drawings, 5 indicates an ordinary trolley-pole which may be arranged in conneetion with a car or vehicle and be operated in connection therewith in any ordinary manner.

6 is a trolley-wheel adapted to contact with a trolley-wire to effect a transmission of the motive current to the motor of said car or vehicle in any usual manner, the said trolleywheel being arranged between ears? 7 of the said pole on a pivotal bolt 8. At the outer sides of the said ears on the said bolt 8 are arranged angular guarding-plates 9, of which 10 indicates the upper rearward extensions, which normally project above the level of the periphery of said trolley-wheel 6 to prevent the wheel from disengaging the wire. Said guarding-plates are held in their normal position of Fig. 1 by U-shaped springs 11, which.

are of curvilinear form and extend from the arm 10 downward to a suitable clip or fastening device 19. on the pole 5 below the ears thereof. The lower ends of said springs are rigidly held by said clip so as not to have any pivotal turning thcreat, the clip being more than a mere pin, and upward from said rigidly-held end the springs each make a broad cuvilinear sweep free from the pole 5 or bolt 8 to a point above the forked end of the pole where said springs engage each its independent angular guarding-plate.

The arrangement of the springs above de scribed permits a greater freedom of move ment of the same and the stress brought to bear on the springs is distributed, so as to permit a free movement of the angular plate Without danger of breaking said spring, and long lateral catching projections due to coiling of the spring is avoided. Said slip 12 provides suitable bearings for two of such springs, one spring for each of the two independent guarding-plates, and the said guarding-plates being thus adapted to move independently one of the other on the pivotal bolt 8, whereby greater eflicicncy and positiveness of protection are secured. Of each of the guardingplates the lower arm 13, which normally lies in approximately horizontal position, is thrown upward to guarding positions when the upper arms 10 strike against crossing wires or the like transverse objects and turn downward to permit a passage of the obstruction.

The pivotal movements of the guardingplates are limited by shoulders or stop projections lt and 15, cast or otherwise formed at the inner sides of the guarding-plates, as shown clearly in Fig. 2. These strike against the pole 5 or the ears 7 thereof, as will be un derstood upon examination of Fig. 1, at the desired limit of pivotal movement.

I am aware that various changes may be made in the construction of my device without departing from the spirit or scope of the invention, and I do not wish to be understood as limiting myself by the positive descriptive terms above employed, except as the state of the art may require.

Having thus described the invention, what I claim as new is-- 1. The combination with the trolley-pole having ears 7 and bolt 8, of a wheel between said ears carried by said bolt and angular plates on the outer sides of said ears, and having arms with limiting projections on their inner sides and springs for holding said plates in normal position, substantially as set forth.

2. The combination with the trolley-pole having ears and a bolt, of a wheel arranged between said ears on said bolt, independent angular plates pivoted on said bolt and having arms with limiting projections on their inner sides, and curvilinear springs rigidly held to the pole at points below said wheel GEORGE W.
